Multislice HELICAL CT SCANNER

APPLICATIONActivionTM16 is a 16-slice Helical CT system that supportswhole-body scanning.The system generates a minimum of 32 slices per 1.5 sec-onds using the Selectable Slice-thickness MultirowDetector (SSMD). In addition, the high-speed rotation mechanism and thefast reconstruction unit of the system allow quick imageacquisition to further improve throughput in CT examina-tions.

FEATURES• Multislice detector

Detection elements with high-power and uniform outputcharacteristics enable a minimum slice thickness of 0.5mm, and accurate isotropic data can be acquired.The adoption of the SSMD method means that high-speed as well as high-resolution scanning are support-ed.The minimum slice thickness is reduced to 0.5 mm, mak-ing it possible to select the desired slice image for scan-ning from among 0.5 mm, 1 mm, 2 mm, 3 mm, 4 mm,and 5 mm, depending on purpose.

• High-speed scanData for 16 slices can be acquired simultaneously ineach scan. For example, scanning of the lung fieldsover a range of 30 cm at a slice thickness of 1 mm canbe completed in 10 seconds or less.Since the acquisition is completed in a short period oftime, this obviously alleviates the burden on the patient,but also improves throughput by eliminating the need towait for the X-ray tube to cool down.

• High-quality imagesIt is now possible to use thin-slice helical scanning forroutine examinations. Based on high-resolution voxeldata, smooth and finely-detailed 3D and MPR imagescan be obtained with the same size in the X, Y, and Zdirections (isotropic). In CT cerebral angiography, forexample, scanning over a range of 40 mm at a slicethickness of 0.5 mm can be completed in 4 seconds andimage processing (such as 3D, MPR, or tomographicimage processing) can be performed for a single volumeacquisition dataset through simple operations.In addition, by stacking the data acquired using thinslices, images with reduced partial volume effects canbe obtained.

• Outstanding operabilityOperability is improved as described below.– In 3D image processing or time-consuming image pro-

cessing such as for regions in which calcified areas aresuperimposed on contrast medium, bone eliminationcan be performed easily while observing referenceimages.

– Most 3D images can be generated using the optimalconditions by simply selecting an appropriate preseticon.

• Selectable image slice thicknessIt is possible to acquire the data for routine examination,detailed examination and to generate 3D images in a sin-gle scan.For example, by performing a helical scan with a 0.5-mmslice thickness, it is possible to generate images at vari-ous slice thicknesses from the same data, such as 10-mm slice images for routine examinations, 5-mm sliceimages for detailed examinations, and 0.5-mm sliceimages for generating 3D images. It is also possible toset the image slice thickness with multiple ranges.For example, by performing a helical scan of the headwith a 0.5-mm slice thickness, it is possible to generateimages with optimal slice thickness for each region in asingle reconstruction, such as 5.0-mm slice images forthe cranial base as well as 10-mm slice images for thecerebral parenchyma.

• Exposure reductionThis system incorporates the quantum denoising soft-ware (QDS) as a standard function, which is effective forreducing patient exposure.The QDS is an adaptive filter that can recognize recon-structed objects. It can perform sharp filter processingfor regions where the degree of change is high, such astissue borders; and smooth processing for regions wherethe degree of change is low (close to uniform). Thismakes it possible to further improve the quality of imagesacquired using normal dosages, and improves the quali-ty of images acquired with small dosages to an imagequality level obtained with normal dosages. As a result,it is possible to reduce the exposure dose for the patient,since the scanning can be performed using the optimaldose for the expected image quality.

• SUREFluoroTM (option)Conventional CT fluoroscopy shows only a single slice,but SUREFluoro (Multislice CT fluoroscopy) permits realtimeimage reconstruction to display 3 images obtained bycombining data from the SSMD. SUREFluoro significantlyimproves operability in biopsy and interventional proce-dures.

• Tilt Helical scanningHelical scanning with gantry tilt, from 30° forward to 30°backward, is available because the system employs theTCOT reconstruction technique.

SYSTEM COMPONENTS AND THEIRFUNCTIONSGantryThe scanner is composed of the gantry and the patientcouch. The scanner uses a fan-shaped continuous X-raybeam to scan the region to be examined. Transmitted X-rays are detected and converted into electrical signals bythe SSMD.The gantry includes the main body and its support mecha-nism. The X-ray tube and the SSMD are mounted facingeach other on either side of the gantry aperture, and the X-ray tube and detectors rotate continuously around theaperture of the gantry. A slipring is employed to transmitpower between the gantry and the rotating X-ray high-volt-age generator assembly.The gantry can be tilted forward and backward in order toperform tilt scanning. Three-dimensional alignment lightsare provided for setting slice positions. Gantry and patientcouch operating controls are provided on both sides of thefront of the gantry housing. The patient guide display indi-cates the scan status to the operator and the patient. TheX-ray high-voltage generator is built into the gantry, andthe system employs a high-frequency inverter for generat-ing and stabilizing the high voltage supplied to the X-raytube. The generator includes electronic circuits for control-ling the speed of the rotating anode in the X-ray tube. Useof a high-frequency inverter system results in high poweroutput combined with excellent stability. In addition, thesystem is compact and light weight.

X-ray generatorThis unit supplies stable high voltage to the X-ray tube unit.The high-frequency inverter method is employed, resultingin a light and compact design. This unit is incorporated inthe gantry.• Max. power: 42 kW

X-ray tubeThis is a large-capacity, high-cooling-rate X-ray tube that isable to withstand continuous operation as in helical scan-ning. • Heat capacity: 4 MHU• Cooling rate: Max. 864 kHU/min

Patient couchThe patient couch is positioned in front of the gantry andsupports the patient. The entire unit moves vertically andthe top moves longitudinally. In an emergency, the couch-top can be pulled out manually with very little effort. Thecouch-top can also be lowered to a minimum height ofapprox. 310 mm from the floor, facilitating transfer of thepatient from a low bed or stretcher.

ConsoleThe console is provided with a hybrid keyboard, a monitor,and a mouse.• Functions for scanning

– Selection of scan parameters– Scanoscope control– Scan control– Remote control of couch-top movement– Remote control of gantry tilt

• Functions for image processing – Window level and window width adjustment– Other mouse-operated image processing functions

OPERATING FEATURES

Patient handling and positioning• The couch-top can be lowered to approx. 310 mm (at

the center of the couch top) from the floor, making it easi-er to transfer the patient to and from a bed or stretcher.

• Alignment lights are provided in the gantry aperture forfast and accurate patient positioning.

• High-precision couch-top positioning is possible from theintegrated console or by manual operation from the con-trol panel and clear digital readouts are provided on thegantry.

• The couch-top can be pulled out manually in an emer-gency.

Scanning• Toshiba's scanoscope function provides a projection

image of the patient for high-precision advance planningof the slice positions.

• The longitudinal length of the scanning field for thescanogram can be adjusted up to 1,750 mm (1,450 mmfor the short patient couch version). Real-time helicalpermits the scan to be aborted at any time. This mini-mizes the patient exposure dose.

• The auto index function allows automatic incrementalcouch-top movement based on the slice positions deter-mined through the scanogram.

• The eXam Plan function allows simple selection of pre-programmed scanning parameters for routine examina-tions, maximizing patient throughput.

• Protocol comments can be saved in each eXamPlanprovideng interactive onscreen instructions for all studiesreducing the need to refer to a separate protocol book.

• The Vari-area function allows the user to pre-select aregion of interest for zooming using raw data, permittingimmediate post-scan analysis. Zooming using raw datayields higher resolution than enlarging an image that hasalready been reconstructed.

• Dynamic and rapid sequence scan modes are provided.• Multislice helical scan acquires raw data by rotating the

X-ray tube continuously while moving the patient continu-ously through the scanner. The volume data acquiredcan be used to reconstruct slices at any desired axialpositions. This scan mode is best used for rapid patientscanning during a single breath-hold and for high-defini-tion three-dimensional and MPR imaging.

• Real-time helical reconstruction mode makes it possibleto observe the images being scanned in real time at amaximum at 12 frames per second. This mode showsany shift in the slice position in real time and helps theoperator to check the scan field on the image, the con-trast study timing, the presence of patient body motion,etc. The patient can therefore be released immediatelyafter scanning.

• The SUREStart function allows the operator to start helicalscanning at the timing of maximum enhancement in con-trast studies. SUREStart monitors the scan from the start ofa contrast study at a certain slice position while measur-ing the changes in CT number on the image being dis-played in real time. When the contrast reaches thepredefined threshold, helical scan automatically starts.This technique ensures optimal contrast enhancement,independent of individual differences in blood flowspeed, and at the same time minimizes the dose of con-trast medium.

Data processing• Rapid reconstruction increases the reconstruction speed

to 0.5 second in 0.75-second scans. (Scan & Viewmode)

• A variety of reconstruction algorithms are available andcan be selected according to the anatomical region tobe examined and the clinical objective of the study.These include algorithms for the abdomen, head, bone,lung, small structures, soft tissues, etc.

Image display and processing• Reconstructed images are automatically displayed

according to the window settings preset in the eXamPlan.

• The window save function allows the user to store animage with window settings different from the ones set inthe eXam Plan.

• Filter parameters can be customized through simple on-screen menu selections. These parameters include thenumber of filtering passes, matrix size, and filter coeffi-cients.

• Images can be rotated and reversed either right/left,top/bottom, or black/white.

• The Multi-frame feature allows up to 16 images to beretrieved and displayed simultaneously on the screen.

• The three-dimensional image display function allowscolor three-dimensional and MPR images in real-time tobe generated from the volumetric scan data acquired byhelical scanning. This results in higher definition andimage quality than images reconstructed from conven-tional single-slice scanning. This is because helicalscanning provides superior data continuity along thepatient axis compared with conventional scanning.

Image storage and archiving• The system is provided with a 217 Gbyte magnetic hard

disk as standard equipment, permitting the on-line stor-age of approximately 100,000 images and 3,600 rota-tions of raw data.

• A 9.4 Gbyte DVD-RAM disk drive is provided as stan-dard equipment. The image storage capacity of theDVD-RAM disk is approximately 16,000 images per disk.

Image filming• Filming of images can be performed manually or auto-

matically from the console.• Automatic filming sends an entire study to the laser cam-

era. Filming is performed in background mode so thatother scanner and image processing functions can beperformed without interruption or delay.

• When T-mode is used, related information items dis-played together with an image (surrounding the image, ina small font) are displayed in the footer area using a larg-er font, permitting not only easier reading but also sim-pler film management.

Note: To use T-mode, the laser imager must support 2048 pixels x 2404 pixels for a 1 x 1 frame.

Patient throughputPatient throughput and cost effectiveness were majorobjectives in the design and production of the system.• The system incorporates a 4.0-MHU X-ray tube with a

very fast cooling rate of 864 kHU/min in actual use.• High-speed scans can be performed in as little as 0.75

second per scan. • Real-time reconstruction is possible in scanoscopy.• CT images can be reconstructed in 0.5 second for 0.75-

second routine scans.• Ease of operation is ensured by incorporating a hybrid

keyboard, mouse-driven menus, and a large color LCDscreen.

• The couch-top can be lowered very near the floor, simpli-fying patient transfer.
